Michael: You might want to think before you reply in the future, rather than criticizing someone for something that's not at issue anyway.
Pat's quick rule of thumb was based on an assumption about BMI. As BMI is derived from height and mass, then height can be derived from BMI and mass. His actual guess as to Paul's height assumes that Paul's BMI is close to the "ideal." Because it's just a rule of thumb, it is, in any case, only a best-case approximation.
